ABSTRACT:
A laser emitting module, a window cap thereof, a laser pointer using the same and a light emitting module are provided. A light emitted from a laser diode excites a solid-state laser medium so as to generate lights of different wavelengths, the wavelength of which is converted in a non-linear optical element so as to emit a laser beam of a short wavelength by second harmonic generation. An optical resonator including the solid-state laser medium and the non-linear optical element is supported by a base member. Heat of the laser diode and the optical resonator is dissipated via a heat sink which is in contact with the laser diode and the base member, thereby stabilizing temperatures of respective elements and thus the generation of the laser beam.
